How're you measuring the current consumption of each stick?

I bought a USB safety meter. You plug this in first, then you put the ASIC in that thing. Typically, the ASIC runs around 4.8-5.0 V, and 1.8-2.0 AMPS. So, gets me the 9W-10W.

Can you measure the voltage across the capacitor for each ASIC chip?

I bought the USB safety meter so I wouldn't have to do it. I tried once with a multimeter, but didn't understand how to measure the voltage correctly.

Finally, do you have a fan on the heatsinks?

Yes. With one ASIC, the fan seems to keep it cool and running fine without intervention for 4+ days.

but then zombied about 3 hours after the building's aircon shut down for the evening.

That's a good point about ambient temp changes. Maybe I need to get a digital thermometer that can record historically.

it's just run happily overnight @ 325 MHz with ASIC voltage of 0.73V.

I'm confused. Mine for voltage is 4-5 volts. I guess I'm confused why you said 0.73V?

both heatsink temp and ASIC temp on the back side of the PCB

you got a point and shoot surface temp gun? how much are those? Maybe I should try positioning the hub, so the ASIC is "standing up" versus on its side.
